    Abstract: A method is provided for fabricating a porous elastomer, the method comprising the steps of: providing a predetermined amount of a liquid elastomer and a predetermined amount of a porogen; mixing the liquid elastomer and the porogen in vacuum until a homogenous emulsion without phase separation is formed; curing the homogenous emulsion until polymerizations of the emulsion is reached, thereby forming a cured emulsion; and removing the porogen from the cured emulsion. The method can advantageously be used for forming biocompatible porous elastomers and biocompatible porous membranes.

    Abstract: A process for obtaining an aerogel from a polymeric material that is in the form a sol-gel in an organic solvent, by exchanging the organic solvent for a fluid having a critical temperature below a temperature of polymer decomposition, and supercritically drying the fluid/sol-gel. The process is carried out in a semi-continuous mode that includes the steps of contacting the initial sol-gel with a stream of the fluid at different pressures and temperatures through n+1 pressure vessels A.sub.0 to A.sub.n that each have an inlet for fluid VI.sub.i and an outlet for effluent VO.sub.i wherein the n+1 pressure vessels are operated dependently on each other through a joint fluid supply system and a joint effluent treatment system so that the respective product in each of the pressure vessels A.sub.0 to A.sub.n is submitted to the fluid in successive steps with pressure and temperature following a curve that never cuts the vaporization curve in the pressure-temperature diagram of FIG. 1.

    Abstract: Supercritical drying has distinct advantages in generating microcellular materials. The dimensional stability of the polymer is not affected on drying because the supercritical process does not go through the two phase path and therefore the effect of capillary forces is absent. This helps in maintaining the morphology of the final polymer structure and better control over cell size.Organic microcellular foams were prepared by polymerizing directly in a near-critical fluid and pursuing the supercritical drying in the same reactor. The critical variables are the choice of a diluent with a strong enough solvent power to stabilize the polymer matrix, but with a low enough critical temperature to permit critical point drying without damage to the polymer matrix.

    Abstract translation: 超临界干燥在产生微孔材料方面具有明显的优势。 聚合物的尺寸稳定性不受干燥影响，因为超临界过程不经过两相路径，因此不存在毛细管作用。 这有助于维持最终聚合物结构的形态并更好地控制细胞的大小。 通过在近临界流体中直接聚合并在同一反应器中进行超临界干燥来制备有机微孔泡沫。 关键变量是选择具有足够强的溶剂能力的稀释剂以稳定聚合物基质，但具有足够低的临界温度以允许临界点干燥而不损坏聚合物基质。
